Question

An electron is moving in circular orbit. The angle between magnetic moment of electron and angular moment of electron is
Choose one:

0°

90°

180°

45°

Answer 1

Hey.

Here is the answer.

As the angular moment will be having the tangential direction with the circular trajectory of the electron and the direction magnetic moment is always circular to the direction of the motion of the charge, so the angle comes to be 90°.

Thanks.
